基于网络结构分析的信阳市绿色基础设施优化研究

Optimization of Green Infrastructure in Xinyang CityBased on Network Structure Analysis

  • 摘要: 以信阳市为案例,依据“中心控制点-连接通道-场地”提取了绿色基础设施系统,然后采用景观阻力分析提取生态廊道并模拟优化路径,最后提出布局优化方案并通过网络结构分析进行验证和提出管控措施.研究结论表明:优化后的α指数由0.11提高到0.37,β指数由1.08提高到1.79,γ指数由0.38提高到0.58;优化后绿色基础设施网络较之前有较高的复杂性和连接性,具有一定的生境网络功能,基本能够满足居民的需要.

     

    Abstract: Based on the case of Xinyang city, the green infrastructure system is extracted according to the “central control point-connecting channel-site”, and then the ecological corridor is extracted by the landscape resistance analysis and the optimization path is simulated. Finally, the optimum scheme and control measures are put forward through the analysis of network structure to verify. The results show that the optimized α index is increases from 0.11 to 0.37, β index is increases from 1.08 to 1.79, γ index is increases from 0.38 to 0.58; the optimized green infrastructure network has higher complexity and connectivity than before, and it has certain habitat network function, which can basically meet the needs of residents.
